FLUID STABILIZER.

Application filed. September 7, 1922;. Serial No. 304,547.

This invention relates to'a stabilizing construction for use in tank cars.

As is well known to those skilled in the art it frequently happens that, when large tank cars filled with oil or other liquids are rounding curves at highspeeds in transit, the liquid contents oi? the cars tend to slosh upwardly and outwardly by centrifugal force, thereby throwing the cars out of balance, and frequently overturning them with disastrous results. I

It is an object of the present invention to arrange within a tank at the sides thereof deflecting shields which will hold the liquid down and in place and preventthe objectionable results heretofore stated.

A further object is to provide a stabilizing structure which does not reduce the capacity of the tank to an objectionable extent nor produce an objectionable increase in the weight of the tank. y r

\Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the conib.i-' nation and arrangement of parts andin the details of construction hereinafter descril ed and claimed, it being understood that changes in the precise embodiment of the mvention herein disclosed may be made within the scope of what is claimed without departing from the spiritof the invention.

In the accompanying drawings the preferred form of the invention has been shown. In said drawings, r Figure l is a side elevation of a tank car embodying the present improvement, a portion being broken away.

Figure 2 is an enlarged transverse section through the tank.

reference, 1 designates a cylindrical tank such as commonly, used by railways for transportation of oil and other fluids. Ar-

ranged within the tank at each side thereof is a deflecting shield inthe form ofiaplate 2 extending longitudinally of the tank and secured at its lower edge to the tank atone side of thebottom' portion thereof; The lower edge ofthe plate is spaced from the side or wall of the tank by blocks 5 so as to permit the return of all fluid to the bottom of the tank. The plate is preferably fiatfor' a portion of its height and then merges into an inwardly and downwardly curved upper portion 3 which isheld fixedly to the tankv 'means therein for ing and outward pressure of liquid contentstions. Referring to the figures by characters of their bottom edges by means of interposed brackets 4: riveted to the plateand to the tank.

The free upper edges of the shield plates come close together I and the upwardly extending flat portions of the plates upward direction and are of course spaced from the side and top portions of the tank. The spacing blocks 5 holdthe bottom edges of the deflecting shields or plates any desired. distances from the wall of .thetank, thus permitting free return of liquid to the bottom of the tank at all times.

When the tank is partly filled with liquid and is'subjected to side pressure therefrom, as while rounding a curve, the liquid,in-

stead of sloshingupwardly along one side .ing plates 2, interposed brackets at, and

preferablyconvcrge slightly in an by removing The upstand- I spacing blocks 5 are then inserted and secured after which the head is replaced.

What is claimed is: V l 1. The combination with. a tank car, of preventing upward sloshwhile in transit and rounding curves, said means lncluding an upstanding plate within each side portion, said plates having indownwardly curvedjupper porwardly and 2. The combination with a cylindrical tank of the portable type, of means therein for stabilizing the liquid contents thereof, saidmeans including plates within the side portions of thetank secured at their lower edges to the tank and extending longitudis nally of the tank, each ofsaid plates having an inwardly and downwardly curvedupper portion. 8. The combination-with a portable cylindrical tank, of stabilizing means therein in cludingsubstantially flat plates in the tank adjaoentthe sides thereof and securedalong and converging upwardly,

7 to the tank, said plates beingfextended longitudinally of th tank 4. The combination with a portable cylindrical tank, of stabilizing means therein including substantially fiat plates in the tank adjacentthe sides thereof and secured along their bottom edges to the tank, said plates being extended longitudinally of the tank and having their upper portions extended inwardly and downwardly toward each other, and means for connecting the upper portions of the plates to and spacing them from the tank.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature this September 4th, 1928.
